? BAG-CRIIMPING DEVICE.

Specification of Letters Patent.

' Patented April 20, 1909.

Application filed January 10, 1906. Serial No. 296,858.

citizen of the United States, residing at fiCleveland,- in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Bag-Crimping Devices, of which the following is a specification.

My invention relates to means for holding, crimping and tying the open ends of bags.

. Itisintended particularly for use in connect1on wlth valve bags.

The drawing is to be taken as in most particulars diagrammatic and illustrative simply of a rude form' of device which can be easily varied at will to carry out the idea.

Where the bag is the measure or where a set of ba 3 are filled with a uniform amount of material, that amount depending on the capacity of the bag, it is obviously necessary to have a uniform method of tying so as to secure, withja given set of bags of a certain size, uniformity of capacity.

In-the' case of valve bags where the bag is filled atone end through a valve opening and is opened and its contents discharged at the other end, it is plainly important that the empty bag should be retied in a uniform manner so that all bags of a given size when filled through the valve shall have the same contents.

Referring to the drawings, Figure 1 is a lan View of a number of holding devices;

ig. 2 is an end view of one such holding device, Fig. 3 is a side view of a holding device with the; bag extended, Fig. L is a similar view with the bag crimped and tied. Fig. 5 is a plan view of the crimping end of the bag.

Like parts are indicated by the same letter in all the figures.

- two parts A is a cross piece suitably supported by the wall or vertical standard C. At intervals along its top the cross piece A is slotted and there is let into it the D D of a springholding device. These parts are extended as indicated and are rounded at their outer ends at D to form a receiving mouth for the bags. These pieces D D are preferably of spring or elastic wood and they tend to force themselves tightly to ether. To facilitate this action,

they may e cut out at E and be adjustably clamped togetherby the bolt F and thumbnut F. G is a stop pin, H H stop pegs, one of them with a cutting edge, J a stop plate and K a flattened spiral spring surrounding the two pieces D D and bearing at one end against the stop pin G and at the other.

against the stop plate J. L is a bag having at one corner an inwardly opening valve L and adapted to be crimped at the top, as in- (heated at L M is the twine with which the bag is tied and it is drawn from the reel M mounted on the stop plate J. As illustrated, one of the pins H has. a cutting edge at H As previously mentioned these parts are in an important sense diagrammatic and some may be dispensed with without afi'ecting the action of the others.

The use andv operation of my invention are as follows: Assuming a series of spring holders like those illustrated in Fig. 1, each with its several parts and its separate reel and ball of twine, the operator will take up an empty bag and by pulling it forward by the edge 0 force it against the action of the spring forward between the two spring pieces backward toward himself in the direction indicated by the arrow in Fig. 3, or if, having the spiral spring in place, he releases the bag and allows the sprin to operate, the result would be that the ag is folded or crimped at its top in a highly uniform manner, the crimped portion being gathered in the recess end formed by the two opposed slots near the ends of the parts D D. The cord is placed with the edge of the bag and stop H H on one side and the plate J on the other so when the bag comes back into the position for tying, the twine will be in position. It can now be tied as indicated in Fig. 4, either by the first or another operator, and can then be jerked out of the holder.

As indicated in Fig. 5, the crimps L are uniform and an arrangement which Wlll bring about this result is, of course, preferable. The tying of the bag canbe accomplished by hand or by machinery in any desired manner.

Where the bag is stretched out in the manner indicated, it can be crimped with great ease and regularity and at a uniform mg members are secured.
